The latest figures are based on a 2011 telephone survey that asked adults their height and weight. For the first time, households with only cellphones were included.

State rates remained about the same, although states with very high rates went from nine to 12. At least 30 percent of adults are obese in Alabama, Arkansas, Indiana, Kentucky, Louisiana, Michigan, Mississippi (the highest, at 36 percent), Missouri, Oklahoma, South Carolina, Texas and West Virginia.

Colorado was lowest at just under 21 percent. Oregon was somewhere in between at 26.7 percent, and Washington was right behind at 26.5 percent.
